Write unit tests for Go backend handlers and services using standard Go testing tools alongside testify. This framework supports table-driven tests and focuses on testing behavior at interface boundaries to ensure high code coverage across all success and error paths.

Set up integration tests for Go repositories using sqlmock for database mocks and testcontainers for real database instances. This approach validates repository layer behavior by testing against both mocked SQL interactions and actual database environments.

Mocking for Go interface boundaries works by generating mock implementations using testify/mock. This allows you to isolate and test behavior at service and repository boundaries without relying on actual external dependencies or database connections.

Yes, you can use httptest with table-driven tests for Go API endpoints. This combination allows you to systematically test HTTP handlers by defining multiple input and expected output scenarios within a single test function.

Use testcontainers when you need integration tests against real database instances, and use sqlmock when you need unit tests that mock database interactions. Testcontainers validates actual database behavior while sqlmock isolates repository layer logic.
